Tom:
Thanks for your message. Edward Shanahan could very well be from James Shanahan family, in Kerry.
That is one of the counties that we believe James came from. His father was named Patrick, who died in 1875. His mother was Eliza Shanahan born 1832, (county unknown) We believe she also came to Chicago with James, and his siblings, (Eliza, Michael and John). James married Margaret Doyle, and the family, mostly city workers, remain in Chicago till today.
Marilyn nee Shanahan does not ring a bell, and we never had a connection to Florida, or Seattle.
Hope this is helpful.
Marilyn
